"Tulips for Tomorrow"

Tulips for Tomorrow

Tulips sing the arrival of springtime to gardeners throughout the world.   Tulips offer a kaleidoscope of colors for all to enjoy—some are early bloomers while others are late.  When my late-blooming, red-orange tulips emerge, I know most tulips are finished for this spring.  These three late-blooming beauties have appeared in my garden every spring for several years.  (I snapped this photo today, April 30, and they appear to be at their peak.)

Although tulip blossoms are gorgeous, their foliage is not spectacular; however, it is important that gardeners allow foliage to remain in the garden, even after petals have fallen and you have removed the stems from each bloom. The foliage will continue to photosynthesize for a month or two, producing sugars (carbohydrates) which will transfer to each bulb beneath the surface.  These carbohydrates are stored in the bulbs until next spring when they provide the energy to push new leaves and blooms to be enjoyed again.

 When foliage is dry and brown, the photosynthesis cycle is complete so leaves can be removed and placed in your compost bin.  Allowing tulip leaves to remain in place until dry sets the stage for large, lovely tulips for tomorrow!

Hatched & Happy in the Hoop House :)

According to Wikipedia, the Red Admiral Butterfly  (Vanessa atalanta) usually winters over in Texas.  However, in early April we discovered several Red Admirals flying around in the LAMMSCAPES!  hoop house; I’m quite certain they wintered over right here in Jackson, Wisconsin.

 As we go about our springtime tasks in the hoop house, it is a pleasure to witness these butterflies flitting about, enjoying warm spring days. They appear to be hatched and happy, and eager for more warm, sunny weather (aren’t we all !!)

Although this photo was taken in my home garden during summer, it is the same Red Admiral species that inhabits North America, parts of Asia and Europe.   Red Admiral is one of many butterflies that visit Wisconsin, and gardeners often observe these beauties sunning themselves on the petals of brightly colored blooms in our gardens.

Don't Give Up on Me!

The song entitled “Don’t Give Up On Me” is a suitable theme song for several perennials, shrubs and trees which thrive in our Southeastern Wisconsin area. While shrubs and trees like forsythia and magnolia herald the arrival of spring with a flush of colorful blooms, many other genus and species remain dormant, exhibiting NO signs of life in early spring. 

Often the crispy, crinkly foliage has persisted through winter, as shown on this photo of smokebush (genus Cotinus) during April.  It is not dead—just dormant.  Late-emerging plants often surprise gardeners when their buds begin to push much later than other plantings.  A few examples of late-emerging plants: 

Blazing Star, Gayfeather  (genus Liatris)  flowering perennial
Butterflybush (genus Buddleia)  marginally hardy perennial in Zones 4,5
Bluestar (genus Amsonia)  flowering perennial
Buttonbush (genus Cephalanthus)  flowering shrub
Bottlebrush Buckeye (genus Aesculus)   flowering shrub
Smokebush (genus Cotinus) flowering shrub
White Fringetree (genus Chionanthus)   small flowering tree (15’ -20’)

Various ornamental grasses (Big Bluestem, Little Bluestem, Fountain Grass and others) are often latecomers in exhibiting spring growth.  Don’t give up—give them additional time before digging and transporting to your compost pile!

Trees in the genus Quercus are typically late to emerge, so while you are inspecting for signs of new growth on your oak trees, your oaks are whispering, “Don’t give up on me!”

Save your plant's tender buds from the cold!

FreezePruf ® reduces risk!
 




Local gardens and gardeners have enjoyed  warm, balmy temperatures throughout  March— a weather pattern virtually nonexistent  during March in years past.   The spring bulbs in bloom, as well as forsythia and magnolias, produce lots of smiles!  Buds are pushing on trees and shrubs all around … spring weather has arrived early in Southeastern Wisconsin!   But then reality sets in… a few days of cold, damp weather, followed by nights with patches of frost .  What can we do to protect the vulnerable new growth on our favorite plantings?

A recently developed product can protect our plants from frost and ice crystals:  FreezePruf®
This amazing liquid can be sprayed on all plant parts until thoroughly wet, including tops and bottoms of existing foliage and flower buds.   Protection should last two to four weeks, depending upon severity of the freeze event. 

The research efforts of botanist, Dr. David Francko ( University of Alabama) who is primarily responsible for this product development, have produced this unique spray for landscapers and gardeners.  He explains the FreezePruf® product enhances each plant’s ability to survive cold, freezing temps.   Ideally, the product should be applied generously  8 – 12 hours prior to an expected freeze event for greatest effectiveness.   

Although this product should not be used on succulents, most  outdoor plants will benefit from a coating of FreezePruf®  (it is both biodegradable  and pet-and-people friendly).    The following link provides lists of plants which have been tested for effectiveness using the FreezePruf® spray for cold protection:  http://pro.liquidfence.com/ecologic/freeze-pruf.html

This product can improve the cold tolerance of plants up to  9º F.   FreezePruf®  is a non-toxic form of “antifreeze” for your plants, and can be reapplied to new growth which emerges after  the initial treatment.  An application of FreezePruf® protects the cell membranes and cell walls of stems and leaves, preventing total destruction , even if temps drop below 32º F.   

NOTE:  FreezePruf® is available as ready-to-use spray or concentrate.   Improving our plants’ cold tolerance during April and May is our best defense against frigid cold temps damaging plant tissue.

"Icing on Cupcakes ... Icing on Conifers!"

Here's a cool & refreshing tip on our warm "spring-like" day.
Remember weather can always change in Wisconsin!


"Icing on cupcakes… icing on CONIFERS!"

Envision a delectable cupcake topped with a mound of fluffy white icing… a perfect marriage of delicious cake and creamy topping.  But icing on conifers??? Although the scene shown here is rather typical during winter in Southeastern Wisconsin, ice glazing definitely is not beneficial to conifers.

Frequently, springtime provides our area with a plethora of weather conditions—particularly snow and ice storms.  Because March/April temperatures can hover near 32º F.  any precipitation that falls has a high moisture content, often creating a thick ice/snow load on conifer branches.

As a homeowner, you may elect to brush excess snow from branches, but please do so very gently, with special care.  Before beginning the snow removal process, inspect branches to determine if icicles have formed at branch tips as shown here.  If icicles appear, do not be tempted to remove snow and ice from brittle branches!  My tree care teacher instructed this action could cause serious damage to conifers’ branches.  Since new growth occurs at branch tips, removing snow (and underlying ice) can cause damage to terminal buds, which are preparing to break dormancy with the arrival of springtime.  

Solution:  Be patient!  Allow sun to melt those ice-encrusted branches slowly. Conifer branches should be resilient enough to recover from a temporary icing condition and will generate fresh growth as warmer spring days arrive.
